IntroductionThe emergence of multidrug-resistant bacterial pathogens has led to a global public health emergency and novel therapeutic options and drug-delivery systems are urgently needed. Cefiderocol is a siderophore cephalosporin antibiotic that has recently been developed to combat a variety of bacterial pathogens, including β-lactam- and carbapenem-resistant organisms.Areas CoveredThis paper provides an overview of the mutational and plasmid-mediated mechanisms of β-lactam and carbapenem resistance, the biochemical pathways of siderophores in bacterial iron metabolism, and how cefiderocol may be able to provide better targeted antimicrobial therapy that escape these drug-resistant mechanisms. We also explore the pharmacokinetics of this new compound as well as results from preclinical and clinical studies.Expert OpinionThere is an urgent need for novel antimicrobial agents to address the emergence of multidrug-resistant pathogens, which are an increasing cause of morbidity and mortality worldwide. Our understanding of multidrug-resistance and bacterial biochemical pathways continues to expand, and the development of cefiderocol specifically targeting siderophore-mediated iron transport shows potential in escaping mechanisms of drug resistance. Cefiderocol, which demonstrates a favorable side effect profile, has the potential to become first-line therapy for our most aggressive and lethal multidrug-resistant Gram-negative pathogens.
